Configure DHCP on a Cisco ASA 5505
Wikipedia.org defines Dynamic Host Configuration Protocol (DHCP) as a
network application protocol used by devices (DHCP clients) to obtain
configuration information for operation in an Internet Protocol network.
This protocol reduces system administration workload, allowing devices
to be added to the network with little or no manual intervention.
The diagram has the network topology. In this network the firewall is the gateway of the 10.16.74.0/24 network. Firewall and Servers will be excluded from the DHCP pool.
First step is to configure the inside (LAN) interface on the 10.16.74.0/24 network
FIREWALL(config)#interface Vlan1
FIREWALL(config-if)#nameif inside
FIREWALL(config-if)#security-level 100
FIREWALL(config-if)#ip address 10.16.74.1 255.255.255.0
Next assign the LAN ports for the correct VLAN in this case port 1 of firewall will be on VLAN 1
FIREWALL(config)#interface Ethernet0/1
FIREWALL(config-if)#switchport access vlan 1
FIREWALL(config-if)#no shut
Lastly, configure the dhcp range and assign it to an interface. Configure DNS servers, one internal and one external in case the internal fails. Enable DHCP on the inside interface
FIREWALL(config)#dhcpd address 10.16.74.15-10.16.74.35 inside
FIREWALL(config)#dhcpd dns 10.16.74.10 4.2.2.2
FIREWALL(config)#dhcpd enable inside
In order to see which devices are receiving DHCP from the firewall run the following command
FIREWALL(config)#sh dhcpd binding
IP address Hardware address Lease expiration Type

Apple Pulls I0n1c's Security and Jailbreak Detection App From the App Store
Apple has pulled an app by hacker Stefan Esser (I01nic) that detected if your device was hacked.
The app could detect security anomalies and whether or not your device was jailbroken.
Here is Apple reasoning for pulling the app...
2.19 - Apps that provide incorrect diagnostic or other inaccurate device data will be rejected
22.2 - Apps that contain false, fraudulent or misleading representations or use names or icons similar to other Apps will be rejected
"We noticed that your app provides potentially inaccurate and misleading diagnostic functionality for iOS devices to the user. Currently, there is no publicly available infrastructure to support iOS diagnostic analysis. Therefore your app may report inaccurate information which could mislead or confuse your users. We encourage you to review your app concept and incorporate different content and features that are in compliance with the App Store Review Guidelines."
Esser says, "they keep ignoring the big question: why kill us and not the other jailbreak detectors or system info tools or iokit using tools..."

Apple in India (Hyderabad)!!!
Good news for indian Apple Developers!
Apple has announced the opening of a new office in Hyderabad that will focus on development of Maps for Apple products, including iPhone, iPad, Mac and Apple Watch. The investment is said to accelerate Maps development and create up to 4,000 jobs.
“Apple is focused on making the best products and services in the world and we are thrilled to open this new office in Hyderabad which will focus on Maps development,” said Tim Cook, Apple’s CEO. “The talent here in the local area is incredible and we are looking forward to expanding our relationships and introducing more universities and partners to our platforms as we scale our operations.”
The new facility, located on the Waverock campus, will provide a world-class, LEED-certified home for the expanding Maps team.
“We are honored Apple chose Hyderabad as a home for its Maps development office,” said Telangana Chief Minister Kalvakuntla Chandrashekar Rao. “This will create thousands of jobs here and is a testament to our proactive approach, quality infrastructure and the excellent talent base we have in the region.”
“Apple is one of the most innovative companies in the world and we are very proud they chose us to partner with for this important project,” said Anup Jindal, RMSI’s CEO. “We are experts in geospatial data and we will be hiring thousands of people from the local area to support this effort.”
Apple says it supports over 640,000 iOS app developer jobs and other positions related to the iOS ecosystem across India. Notably, the company just announced an iOS app design and development accelerator in Bengaluru as part of a new initiative to support developers creating apps in India.
